PCI eXtensions for Instrumentation (PXI) is a PC-based platform that offers a high-performance solution for measurement and automation systems. It will be referred to as parameter analyzer here. The parameter analyzer has mechanical, electrical, and software features that define complete systems for test and measurement, data acquisition, and manufacturing applications. It is controlled from the computer using the "LabVIEW" program. LabVIEW is a graphical programming environment used for measurement, test, and control systems. Use of the parameter analyzer is limited by the LabVIEW software. Currently the primary use for this parameter analyzer is to measure and analyze transistors on wafers, but with more software it could also be used for other applications. The instructions below are the procedure for analyzing a transistor on a wafer.
